Hyundai and Kia Accessories: What's Actually Worth Fitting
CarMoods TeamHyundai and Kia sit under the same corporate group, share a lot of underlying engineering, and between them cover a huge slice of Australian driveways — from a first car like the i30 or Rio through to a family Tucson, Sportage, Santa Fe or Sorento, and now a growing run of EVs like the Ioniq 5, Ioniq 6 and EV3. What the two brands don't share is a strong aftermarket accessories culture the way some marques do. Dealer option lists are thin, and generic "universal fit" parts sold on big marketplaces often don't actually match the wheel diameter, belt geometry or door pocket they claim to. This guide sticks to what's genuinely worth fitting across the Hyundai and Kia range, starting with the two things you touch on every single drive: the wheel and the seat.
Get the Steering Wheel Feeling Right
Factory wheels on most Hyundai and Kia models use a durable but slippery leatherette that hardens in cold weather and turns tacky once cabin temperatures climb — a real problem in an Australian summer, where a car left on the street for half an hour can easily push past 60°C inside. A well-fitted cover changes that texture immediately and shields the factory leather underneath from UV cracking. Wheel diameter also varies more than owners expect: smaller hatches like the i30 and Rio typically sit around 36cm across, while SUVs such as the Santa Fe and Sorento run closer to 39–40cm, so it's worth measuring rather than assuming a universal cover will sit flush.
Whichever finish you prefer, our full steering wheel cover sizing and fit guide walks through measuring your rim properly, and the steering wheel covers collection has options beyond these two if neither finish suits your interior.
Comfort for the Seat You're in for Hours
Factory headrests on both brands are angled for an average-height driver, which leaves taller drivers pushing their head forward against a gap, and leaves anyone doing regular longer drives without real lower-back support once the factory lumbar bolster compresses. A dedicated neck and lumbar cushion fills that gap without needing tools, and it's one of the few accessories most owners notice within the first ten minutes of driving.

Seat Belt Pads Matter More on Some Models Than Others
Seat belt geometry isn't identical across the range, and it's worth understanding why before assuming a pad is just a comfort nicety. The Ioniq 6's sloped, coupe-like roofline pulls the belt across the collarbone at a sharper angle than a boxier SUV does, which means the webbing digs in more noticeably on a long drive — a shoulder pad genuinely earns its place here rather than being purely decorative. On the Tucson and the smaller i10/i20/i30 hatches, the effect is milder but still present, particularly for shorter drivers where the belt sits higher across the neck.

Protecting the Factory Key Fob
Hyundai and Kia proximity fobs are mostly moulded ABS plastic, and that plastic goes glossy and brittle with pocket carry faster than owners expect — cracks tend to appear at the seam within a couple of years, especially if the fob spends hot afternoons sitting on a dashboard. A leather or metal case protects the shell while still leaving the buttons usable, and it has a second, less obvious benefit: it stops the buttons being pressed accidentally in a tight pocket or bag, which slowly drains the fob's coin-cell battery over weeks without you noticing until it's flat.

Our separate guide to key fob covers explains how to pick a case that doesn't block the fob's proximity sensor, which matters more on newer Hyundai and Kia models with passive keyless entry.
A Boot Liner That Handles Whatever the Third Row Throws at It
The Sorento's boot is a genuinely awkward shape to protect properly, because it needs to work whether the third row is folded flat or in use — a liner that curls up at the edges or slides forward under braking isn't much use to anyone. A purpose-cut liner with a raised lip and a rubberised backing grips the factory carpet, contains spills and mud, and lifts out in one piece for a hose-down rather than needing to be scrubbed in place.

Some of the cheapest accessories do the most to avoid an expensive trip to a panel shop. A thin, adhesive-backed anti-shock pad fitted to the door edge absorbs the knock from a neighbouring car door in a tight shopping centre carpark — the kind of ding that's invisible until you notice the paint chip weeks later. It sits flush and disappears once the door is closed, so it doesn't change how the car looks. Pair it with a compact auto-folding umbrella kept in the door pocket or glovebox, and you've covered two of the most common small annoyances of Australian car ownership: carpark dings and being caught out in the rain.
Both fit naturally alongside the rest of a road trip essentials kit if you're setting one up, or browse the wider interior accessories collection for more small fixes like these.
What to Fit First if You're Working to a Budget
If you're not doing all of this at once, order matters. Start with the steering wheel cover and a key case — both are inexpensive, protect a factory part you touch every single day, and make the biggest difference to how the car feels within the first week. Next, add a neck and lumbar cushion or a seat belt pad if you're doing regular longer drives; these are the accessories owners most often say they wish they'd bought sooner. A boot liner comes next if you're regularly carrying kids, pets or cargo — it's more about protecting resale condition than daily comfort, so it's fine to wait. Door guards and an umbrella are the easiest to leave until last; they're useful insurance rather than something you'll notice missing on a short drive.
Frequently Asked Questions
1. Do Hyundai and Kia accessories fit interchangeably between the two brands?
Sometimes, but not automatically. The two brands share a corporate parent and a lot of underlying engineering, which is why steering wheel dimensions and key fob shapes often overlap. Always check the specific models listed on a product page rather than assuming a Hyundai part will fit a Kia, or the other way around.
2. How do I know what size steering wheel cover my Hyundai or Kia needs?
Measure the outer diameter of the rim with a soft tape measure, going around the thickest part of the wheel. Smaller hatches generally sit around 36cm, while larger SUVs run closer to 39–40cm, though it's worth confirming against the exact figure on the product page for your model.
3. Will a leather key case stop my key fob's buttons from working?
No — a well-designed case is cut so the lock, unlock and boot-release buttons stay accessible through the leather or a moulded cutout. It's worth checking the product photos before buying if your fob has an unusual button layout.
4. Is a seat belt pad worth it if I don't drive an Ioniq 6?
Yes, though the benefit is more noticeable on some models than others. Anyone who finds the belt digging into their neck or collarbone on a long drive — common on the Tucson and the smaller hatch range too — will feel the difference, even if the Ioniq 6's sloped roofline makes the issue more pronounced.
5. What's the single best first accessory for a new Hyundai or Kia?
A steering wheel cover. It's the cheapest upgrade on this list, it's the part of the car you physically touch the most, and it protects the factory wheel from UV damage from day one.
Hyundai and Kia don't make it easy to find accessories that actually fit, but the range across both brands is wider than it first looks once you know where to search by model rather than by badge. Start with the wheel and the key you handle daily, add comfort for the drives that run long, and round it out with the small protective extras that save a repair bill later.
